We describe an adaptive routing mechanism based on the energy consumption speed of nodes for on-demand routing protocols in mobile ad-hoc networks. Our algorithm allows a fairly energy consumption during route establishment by building routes that are lower congested than the others. To do this, the congestion information is obtained from a computed cost that depends mainly on the energy consumption speed. The main features of our mechanism is that it is simple, efficient and it can be applied for any on-demand routing protocol. We evaluate through simulations the performance of the AODV routing protocol including our scheme (resulting to a new routing protocol that we call AODV-energy) and we compare it with the basic AODV routing protocol. Results show that our new concept outperforms the basic AODV. Indeed, our scheme reduces for more than 20% the total energy consumption and decreases the mean delay specially for high load networks while achieving a good packet delivery ratio. Moreover, the simplicity of the mechanism enables the design of cheap implementations.
